Figure 6
Square of [sigma]Denzo as a function of the corresponding measured intensity I taken from the first frame of the multi-image experiment. The solid line corresponds to the parabolic fit (using equation 3[link]) and the dotted line represents the fit line shown in Fig. 3[link] using the squared r.m.s.d. values as a function of the extrapolated intensity I0. The minimum intensity used was 1500 ADUs.  [article HTML]
